The annual costume party and fundraiser is a charity benefit for Starlight, a US-based children’s health charity. Starlight provided free event tickets to hundreds of seriously ill children and their families who are supported by LA-area children’s hospitals.

The event featured a ton of games, crafts, food, toy giveaways and live performances from Butterscotch, Leftover Cuties, Mahkenna, Aussie Youth and Le Petit Cirque.
